Application filed September 16, 1912.

Patented June 9, 1914.. Serial No. 720,477.

To all whom if; may concern Be it known that l, Dniamo Bnnvn'r'ri. a subject ol the King of Italy. residing in the borough of ivlanhattan, city, county, and State of New York, have invented certain ne and useful .lnu'n'ovemenjts in Jewel-Settings, of which the following is a specification, reference being had to the accmnpanying drawings.

This invention relates to improvements in jewel settings; and an object of this invention is to provide a jewel setting which will be simple in construction. ctnnparatirely cheap in n'ninutai'zture and efficient, durable and reliable in (nperation and use.

Another object of this invention is to provide a jewel setting which will require a minimum of labor in setting and securing the stones in place.

Another object of this invention is to provide a jewel. setting of which the stoneretaining prongs will be so hidden as to be practically invisible and which will, therefore, have a greatly improved appearance over the settings now on the market.

A further object of this invention is to provide a jewel setting the parts of which will not. become entangled with the clothing of the wearer oi' the setting.

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure l is a plan View of a :lraginent of my new setting; 2 is a section on the line ;-il\. of F 1; Fig. 3 is a section on the line BB of Fig. 1; Fig. l is a perspective View, partly in section, of a f agment oil my new setting; Fig. 5 is a 'l raginentary perspective View of my new setting, showing the stones in place; Fig. 6 is a :t'ragincntary view of a modified form oil setting in which my invention is embodied and in which some oil? the stones are shown in place; Fig. 7 is a plan View o'l another modified form of setting embodying my invention, some ojli the stones being shown in place; and Fig. 8 is a View similar to Fig. t and shows still another modified form of this invention.

My new setting is preferably stamped by means of suitable dies from strips of sheet metal a. By means of these dies there are formed the cup-shaped. seats 7); and from the parts lying between these cup-shaped seats Z) there are struck up by the dies at the time of the formation of the latter the prongs or claws (5. These prongs or claws (l are so arranged that when they are pressed down into place, each prong or claw engages two stones lying side by side between the ends of the setting; and the seats for the stones 2 are located so closely together that the stones within them lie so closely adjacent that each prong (Z is enabled to engage two stones as shown in Fig. It is to be observed that the openings f left by the striking up of the claws lie wholly between the seat of the stones and that the metal 5 lying outside of these seats is not marred or mutilated by openings and is left entirely available for ornamentatiom thereby insuring a setting oil good appearance. The openings f serve to lessen the stiffness of the strip a oi? sheet-metal, which may be readily bent into the desired shape. lvloreover,

\ these openings 1" serve as vents for the washwater used in cleaning the stones.

In Fig. 6 there is shown part of a setting in the form of a cornered (or polygonal) piece, the sides /t, i, meeting at a corner j. The stone 7,; at the corner is preferably held also by means of claws or prongs rZ struck up fit-0111 the metal in the corner. In this case no cup-shaped seats Z) for the stones are pr vided but the prongs are struck up from the metal of the strip and the stones 6 between the corners are. placed so close to gether that the claws or prongs lying between the stones are enabled to engage two stones. hl orecwer, as shown in this figure, the prongs or claws d need not be pointed but may be rounded.

in Fig. 7 there is shown a substantially oval-shaped setting in which no seats are termed vtor the stones, which are placed so close together that the intermediate claws or prongs l engage two of the closely adjacent stones c which lie between the endstones at. These end stones may be held by means of a single prong (Z or by means of two prongs (7, as may be found most desirable. the end-prongs (5*. being struck up from the material oil: the strip.

When the stones are put into position, and the prongs (Z are bent down into retaining position it will be :t'ound that the prongs are so hidden as to be practicably invisible and the appearance of the setting is greatly im proved by this substantial invisibility of the prongs 1. Again, the appearance oil the setting improved by the fact that the prongs cover the openings j" formed by their being struck up from the metal, since the metal from which the prongs (Z are struck up lies wholly between the seats of the stones and the openings f do not extend out into the metal 9 beyond the seats Z). There fore this metal 9 beyond the seats Z) may be used for purposes of ornamentation, the appearance of which will not be detracted from by reason of openings therein which would mutilate or mar the setting. Since each pair of prongs (Z engage a pair of stones it will be seen that the labor of setting the stones 6 will be greatly reduced; and, moreover the initial cost of the dies will also be less than in the case in which each stone is held by four prongs which engage only that stone and no other as is the common practice today in the setting of jewels when a series of stones are set side by side.

In Fig. 8 there is shown a setting in which the inner or lower face of the prongs or claws J is concayed or dished so that the prongs d are convened upwardly and hare a rounded appearance and give to the setting an appearance of ornamentation. These prongs d are also rounded at their inner ends and they are struck up in part from the upper portions of the walls of the cup-shaped seats as will be apparent from an inspection of Fig. 8 and particularly with reference to the holes 7 which are left by striking up these prongs d. This taking of some of the metal from the walls of the cup-shaped seats 5 permits the base portions of the prongs d to be set in closer together and nearer the part c lying between them. However the seats may be on fiat metal, as is shown at Z) in Fig. (3 and at 5* at Fig. 7 where the stones are shown omitted for the purpose of giving a clear View of the seats b, 6*.

I claim:

1. A. jewel-setting comprising a sheet having a pair of seats for the stones said sheet extending a substantial distance outwardly from the seats; and a prong struck up from the material between the seats and bent to a position substantially in the plane of the sheet; said prong lying substantially entirely between the seats and being arranged to engage simultaneously both the stones mounted therein and to conceal the opening iade in the sheet by the prongs being struck up therefrom.

:2. A jewel setting comprising sheet having a pair of seats for the stones said sheet extending a substantial distance outwardly from the seats; and a pair of reyersely-disposed prongs which are struck up from the mate "ial between the seats and bent to a poition substantially in the plane of the sheet; said prongs lying substantially entirely between the seats and being arranged to engage siinultaneously both the stones 1nount ed therein and to conceal the openings made in the sheet by the prongs being struck up therefrom.
